it will be the use full to the all nursing, medical students. to know about the healthy life style and daily use as well as importance of nutrition in over life.
4. NUTRITION SCREENING
• Growth monitoring or home-based care
• Measuring weight and height
• Pitting edema
• Mid upper arm circumference
• Special training
5. DEFINITION OF NUTRITIONALASSESSMENT
Nutritional assessment is the
interpretation of anthropometric ,
biochemical (laboratory), clinical
and dietary data to determine
whether a person or groups of
people are well nourished or
malnourished.
6. OBJECTIVES
• To assess the severity and geographical distribution of malnutrition
• To identify individuals or population groups at risk of becoming
malnutrition
• To identify and analyze the economical factors that are directly or
indirectly responsible.
• To suggest appropriate corrective measures or to develop suitable
health care programmes.
7. • To provide factual evidence for the incidence of malnutrition to
concerned authorities.
• To determine the impact of nutritional programmes.
• To assess the degree of malnutrition of preschool and school going
children.
8. THE ABCD METHODS
Nutritional assessment can be done using the ABCD methods. These
refer to the following :
A. Anthropometry
B. Biochemical/biophysical methods
C. Clinical methods
D. Dietary methods
9. A. ANTHROPOMETRY
• Anthropometry- anthropo means ‘human’ and metry means
‘measurement’.
• Uses several different measurements including length, height , weight
and head circumference.
10. Length
A wooden measuring board(also called sliding board) is used for
measuring the length of children under 2 yrs old to the nearest
millimeter
Measuring the child lying down always gives readings greater than the
child's actual height by 1-2 cm.
11.
12. Height
• Measured with the child or adult in a standing position(usually
children who are two years old more).
• Head should be in the Frankfurt position(a position where the line
passing from the external ear hole to the lower eye lid is parallel to
the floor).
• The shoulders, buttocks and the heels should touch the vertical stand.
• Either a stadiometer or a portable anthropometric can be used for
measuring. Measurements are recorded to the nearest millimeter.
13.
14. Weight
A weight sling (spring balance), also called the ‘salter scale’ is used for
measuring the weight of children under two year old, to the nearest 0.1
kg.
In adults and children over two years a beam balance is used and the
measurement is also to the nearest 0.1 kg.
15. In both cases a digital electronic scale can be used if you have one
available.
Do not forget to re-adjust the scale to zero before each weight. You
also need to check whether your scale is measuring correctly by
weighing an object of known weight.
16. The head circumference (HC)
• Measurement of the head along the supra orbital
ridge(forehead)anteriorly and occipital prominence(the prominent
area on the back part of the head) posteriorly.
• Measured using flexible, non stretchable measuring tape around
0.6cm wide.
17. • HC is useful in assessing chronic nutritional problems in children
under two year old as the brain grows faster during the first two years
of life.
• But after two years the growth of the brain is more sluggish and HC
is not useful
18. an index is a combination of two measurements or one
measurement plus the persons age
• Weight-for –age is an index used in growth monitoring for assessing
children who may be underweight. You assess weight-for –age of all
children under two years old when you carry out your community-
based nutrition(CBN) activities every month.
19. • Height –for-age is an index used for assessing stunting (chronic
malnutrition in children). Stunted children have poor physical and
intellectual performance and lower work output leading to lower
productivity at individual level and poor socioeconomic development
at the community level.
20. • Body mass index is the weight of a child or adult in kg divided by
their height in metres squared:
BMI= weight(kg)
(height in meters)2
Birth weight is weight of the child at birth and is classified as follows:
More than 2500 gram= normal birth weight
1500-2499 gram= low birth weight
Less than 1500 grams = very low birth weight
21.
22. • An indicator is an index (for example, a scale showing weight for
age, or weight for height) combined with specific cut-off values that
help you determine whether a child is underweight or malnourished.
23. • Body mass index (BMI) is the weight of a person in kilograms
divided by their height in meters squared.
• A non-pregnant adult-BMI is 18.5 and 25 kg/m2
• If an adult person has a BMI of less than 16 Kg /m2 they will not be
able to do much physical work because they will have very poor
energy stores.
• In addition they will be at increased risk of infection due to impaired
immunity.
24. VALUE FOR BMI FOR ASSESSING ADULT
NUTRITIONAL STATUS
BMI( Kg/m2)cut-offs Nutritional satuse
More than 40.0 Very obese
30.0-40.0 obese
25-29.9 overweight
18.5-24.9 Normal
17-18.49 Mild chronic energy deficiency
16-16.9 Moderate chronic energy deficiency
Less than 16.0 Sever chronic energy deficiency
25. • An accurate way to measure fat-free mass is to measure the mid
upper arm circumference(MUAC).
• The MUAC is the circumference of the upper arm at the midway
between the shoulder tip and the elbow tip on the left arm.
• The mid- arm point is determined by measuring the distance from the
shoulder tip to the elbow and dividing it by two.
• A low reading indicates a loss of muscle mass.
26.
27.
28. Target group MUAC Malnutrition
Children under five 11-11.9 Moderate acute malnutrition
<11 cm Severe acute malnutrition
Pregnant woman/adults 17-21cm Moderate malnutrition
18-21cm with recent weight
loss
Moderate malnutrition
<17 cm Severe malnutrition
< 18 cm with recent weight loss Severe malnutrition
29. CLINICAL METHODS
• Clinical methods of assessing nutritional status involve
• Checking signs of deficiency at specific places on the body
• Asking the patient whether they have any symptoms that might
suggest nutrient deficiency from the patient.
30. Clinical signs of nutrient deficiency include:
Pallor (on the palm of the hand or the conjunctiva of the eye)
Bitot’s spots on the eyes
Pitting oedema
Goiter and severe visible wasting
31. • In order to determine the presence of oedema,
• You should apply normal thumb pressure on both feet for three seconds
(count the numbers 101,102,103 in order to estimate three seconds without
using a watch).
• If a shallow print persists on both feet, then the child has nutritional
oedema(pitting oedema).
• You must test for oedema with finger pressure because you cannot tell by
just looking.
32.
33. Bitot’s spots
• These are a sign of vitamin A
deficiency.
• Look at the figure ;as you can see,
these sports are a creamy colour and
appear on the white of the eye.
Goitre is a swelling on the neck and is
the only visible sign of iodine deficiency
34. OTHER CLINICAL SYMPTOMS
Visible severe wasting :
In order to determine the presence of visible severe wasting for
children younger than six months, you will need to ask the mother to
remove all of the child’s clothing so you can look at the arms, things
and buttocks for loss of muscle bulk. Sagging skin and buttocks
indicates visible severe wasting
35.
36. Sign/ symptom Nutritional abnormality
Pale: palms, conjunctive, tongue
Gets tired easily, loss of appetite shortness of
breath
Anemia : may be due to deficiency of iron, folic,
vitamin B12, acid , copper, protein or vitamin
B16
Bitots spots Vit A deficiency
Goitre Iodine deficiency disorder
37. DIETARY METHODS OF ASSESSING NUTRITIONAL
STATUS
• Dietary method of assessment include looking at past or current intakes of
nutrients from food by individuals or a group to determine their nutritional status.
• You can ask what the family or the mother and the child have eaten over the past
24 hours and use this data to calculate the dietary diversity score.
• Dietary diversity score is an indicator of both the balance of nutrient
consumption and the level of food security (or insecurity) in the household.
• The higher the dietary diversity score in a family, the more diversified and
balanced the diet is and the more food-secure the household.
38.
39. • As part of the dietary assessment you should also check the salt
iodine level of household using the single solution kit.
• This enables you to determine whether the salt iodine level is 0, more
than 15 parts per million (ppm) or less than 15 PPM.
• Normally, an iodized salt should have iodine level of more than 15
PPM to be effective in preventing iodine deficiency and its
consequences.
